OF TROY, OHIO ANTICLOGGING DEVICE FOR MOWERS.

Application filed March 18, 1918.

To all whom it may concern:

Be it known that I, ARTHUR M. COLLINs, a citizen of the United States, residing at Troy, in the county of Miami and State of Ohio, have invented a new and useful Improvement in Anticlogging Devices for Mowers, of which the following is a specification.

This invention relates to a new and useful improvement in anti-clogging devices for mowers.

The principal object of the invention is to provide a device which may be readily and firmly attached to the dividing shoe of a mower, for bending Or turning over tall grain, grass and other growth which would otherwise, when out, pass over the top of the swath board and lie in the path of the inner shoe to clog the machine during its next round. In thus bending or turning down the tall growth, my device presents it in such a position to the sickle bar that, after it is cut, it will be swept aside by the swath board to form a clear path between the cut and uncut grain, the latter remain ing in an upright position. Accordingly, my improved device not only provides a clear path for the inner shoe of the mower during the succeeding round of the machine, but it leaves the field clean and unmarred by uncut growths.

The referred form of embodiment of my invention is illustrated in the accompanying drawings, of which Figure 1 is aside elevation of my improved device attached to the dividing shoe and swath board of a mower. Fig. 2 is a side elevation of the device itself. And Fig. 3 is a bottom plan view thereof.

Throughout the specification and draw ings, similar reference charactersdenote corresponding parts.

In a detailed description of the preferred form of embodiment of my invention, the numeral 1 designates the outer or divider shoe of a mower, containing a large open ing 9. which receives the end of a sickle bar 3 for attachment to said shoe by means of a fastening element 4. Secured to the rear end of said shoe by means of screws 5 and a bolt 6, is a swath board 7. (See Fig. 1.)

It has been found by experience that the shoe 1 is too low to present tall growth to the sickle bar so that, after being cut, it will not fall over the top of the swath board 7 to Specification of Letters Patent.

. the inner shoe of the mower during the next round of the machine.

Referring to Figs. 2 and 3, the numeral 8 designates an upwardly curved runner rod which terminates at its lower end in an outwardly flaring tubular portion 9 adapted to be forced on the pointed front end 10 of the shoe 1. Integral with, and curving downwardly and inwardly from, the runner rod 8 just above its tubular end 9, is a branch rod 11, terminating at its lower end in a rightangled ear portion 12 containing an aperture 13 adapted to receive the fastening element 1, preferably a bolt.

Integral with, and curving downwardly and inwardly from, the runner rod 8, from a point therein above the branch rod 11, is a branch rod 14: which terminates at its lower end in a flat circular car 15 containing a central aperture 16 adapted to receive the bolt 6. (See Figs. 1 and 2.) The branch rods 11 and 1 1 not only serve to brace the runner 8, but also cooperate therewith in maintaining the uncut growth in a vertical position at the edge of the path which is cleared for the inner shoe of the mower.

The device just described is readily and firmly applied to the shoe 1 and swath board 7 as follows: The tubular end 9 of the runner 8 is forced on the projecting end 10 of the dividing shoe 1, so that the car 12 of the branch rod 11 may be brought to a position to receive the bolt 4, and the car 15 of the branch rod 14: to a position to receive the bolt 6. After the latter has been extended through the aperture 16 in the ear 15 of the branch rod 14, a nut 17 is applied to said bolt 6 and tightened to firmly secure said branch rod to the swath board 7. A nut 18 is also applied to the bolt 4: after it has been passed through the aperture 13 in the ear 12 of the branch rod 11, and tightened to firmly secure the latter rod to the shoe 1. (See Fig. 1.)

When the anti-clogging device is thus secured to the shoe and swath board, the run ner 8 will ride over the tall grain, grass or other growth, turning or bending it down to such an extent that, after it is cut by the sickle bar, it will not fall over the top. of the swath board, but will be caught and swept aside by the latter to provide .a clear path for the inner shoe of the mower during the succeeding round of the machine. Otherwise, the mower would soon be clogged by growth passing over the top of the swath board to encounter the inner shoe on its next round, necessitating the stopping of the machine on that round to remove the clogging matter and thereby delaying not only the clogged machine but other mowers that may be behind it. But where my improved attachment is employed, there is no danger of the machine being clogged by tall growth passing over the top of the swath board, nor will any uncut grain, grass or other growth be left on the field after it has been mowed.

Having described my invention, I claim:

1. In a device of the type specified, the combination with a dividing shoe having a pointed front end, of a swath board secured to said shoe, a runner removably secured to, and curving above, the pointed end of said shoe, a bracing arm extending rearwardly from said runner and connected to the rear portion of said shoe, and a second bracing arm extending rearwardly from said runner and connected to the swath board, substantially as described.

2. In a device of the type specified, the combination with a dividing shoe having a pointed front end, of a swath board secured to said shoe, an upwardly curved runner removably secured to the pointed endof said shoe, a branch rod curving downwardly and inwardly from the lower end of said runner and connected to said shoe behind and below the point of connection of the runner thereto, and a second branch rod above the first named one, curving downwardly and inwardly from said runner and connected to said swath board, substantially as described.

3. In a device of the type specified, the combination with a dividing shoe having a pointed front end, of a swath board secured to the rear portion of said shoe, a central fastening element extending through said swath board and shoe, a sickle bar at right angles to said shoe and projecting into an opening in the latter, a vertical fastening element connecting said sickle bar to the shoe, an upwardly curved runner rod having a tubular lower end to be forced upon the pointed end of the shoe, a branch rod curving downwardly and inwardly from the lower end of said runner rod, a right-angled car on the inner end of said rod having an aperture, the end of the vertical fastening element above the sickle bar, being of sufficient length to extend through the aperture in said ear, a nut on said fastening element to press said oar firmly against said sickle bar, a second branch rod above the first one, curving downwardly and inwardly from the runner rod, and an ear 0nthe inner end of the second rod containing an aperture, the end of the central fastening element beyond the swath board, being of sufficient length to extend through the aperture in the second ear, and a nut on the central fastening element to press said second ear firmly against the swath board, substantially as described.

In testimony whereof I have hereunto set my hand this 14th day of March, 1918.
